Many advanced users stack several compounds in order to get maximum results from their cycle. Normally when your stacking these types of supplements its best to use single compounds instead of premixed stacks. The problem with using a premixed stack is you may get more of one compound than you want. Most of these products have sweet spots. Lets use h-drol for an example according to many of the forums out there 75mg is the sweet spot for this compound. Now lets say you have a halodrol product that is mixed with 10mg of Methylstenbolone. In order to get the proper amound of hdrol you will get more than the recommended dose of M-sten.
In fact, GW1516 has not shown any significant side effects. There is no hormones suppression, no toxicity and no other common side effects. The only thing that should be noted is that GW1516 significantly activates metabolism and contributes to the rapid consumption of glycogen during exercises, so do not exceed recommended dosages; otherwise signs of hypoglycemia (weakness, drowsiness, hunger, muscular cramps, in severe cases - loss of consciousness) may occur. If you feel some of these signs, immediately eat something sweet (containing fast carbs).
